Chandler}12/JH.23.11.37. re Phantom III Clutch GL.{G. Linnett}864. With reference to the 6 clutch plates we are making experimentally, please use the R.R. type flat head rivets instead of the countersunk head rivets shown on drawing, and drill the facings accordingly. This is because we have a quantity of the R.R. made rivets in stock. Also please fit two with Ferodo S.7409 and the other four with Thermoid as originally instructed.
